Problems solved by technology

However, the common thermal insulation bricks on the market have more or less problems of poor waterproof effect and low mechanical strength, which restricts the use of thermal insulation bricks.
[0003] Heat insulation bricks achieve the effect of heat insulation by blocking solar heat radiation, resulting in a long time, especially in summer, the surface temperature of heat insulation bricks exposed to sunlight for a long time will increase significantly, and long-term high-temperature baking may cause insulation hot brick cracks

Abstract

The invention relates to the technical field of building materials, in particular to a multifunctional building material and a preparation method thereof. The multifunctional building material provided by the invention comprises, by mass, 10-50% of an inorganic gel material, 20-60% of a lightweight porous material, 1-10% of inorganic powder, 1-5% of an olefin polymer, 3-10% of an ethylene-vinyl acetate copolymer, 5-35% of a polymer binder and 0.1-1.5% of a release agent. The prepared multifunctional building material has good heat resistance and mechanical strength at high temperature; the weight of the material per unit volume is further reduced while the mechanical strength of the building material is not affected; and the multifunctional building material further has good waterproof performance and heat preservation and heat insulation performance, and is an energy-saving, low-carbon and environment-friendly multifunctional building material.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a multifunctional building material and a preparation method thereof. Background technique [0002] With the development of economy and society and the improvement of people's living standards, people have higher and higher requirements for the comfort of the living environment. In order to ensure that the residence has a good effect of warming in winter and cooling in summer, it is often used To special building materials such as insulation bricks. However, the common heat insulation bricks on the market have more or less problems of poor waterproof effect and low mechanical strength, which limit the use of heat insulation bricks. [0003] Heat insulation bricks achieve the effect of heat insulation by blocking solar heat radiation, resulting in a long time, especially in summer, the surface temperature of heat insulation bricks exposed to sunlight for a long time wi...
